Glue?

I want to glue a small piece of foam to the end of a piece of flourocarbon. Poke a hole in the foam and insert the tippet material.... maybe an 1/8 of an inch contact. Any thoughts on what might bond those best?
Thanks

I' not real sharp on the fly tying end of things but I sorta figure those were the glue choices. The poke thru burn idea is certainly worth a try.

What I'm trying to do is suspend an emerger at a particular depth. I thought a short piece of flouro would be as invisible as it gets and the a very small piece of foam could be the micro bobber. I have seen some flies extended parachutes that do what I'm trying to do but wonder if the was an easier more reliable approach. I also want to hang below the surface lower that a parachute will work. I'm thinking if the emerger is what the fish are on the will overlook the micro bob. This is for moving water and the image is just so you can see the idea. The tippet would still be tied directly to the fly with a tiny loop knot. If I put a thingamaboober this close to a fly it would spook the fish. Call me crazy but I thought it was worth a try....
